In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, so that those skilled in the art can further understand the present invention, the following will implement the present invention in conjunction with the embodiments of the present invention. The technical solutions in the examples are clearly and completely described. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
一种双路输出的制冷采暖热水三联供空气源热泵系统，包括由压缩机1、空气热吸热系统4、供热系统以及连接管路组成的热泵循环机组，热泵循环机组的连接管路中充有冷媒介质，在空气热吸热系统与供热系统之间的管路上串接有膨胀阀6和过滤器5，所述供热系统包括采暖系统3和生活热水系统2，A double output air source heat pump system for cooling, heating, and hot water triple supply, including a heat pump cycle unit composed of a compressor 1, an air heat absorption system 4, a heat supply system, and connecting pipelines, and the connecting pipeline of the heat pump cycle unit The medium is filled with a cold medium, and an
所述供热系统包括接在热泵循环机组中的具有双路输出的罐壳，罐壳设有冷媒进口和冷媒出口，冷媒介质走壳程，罐壳内设有采暖系统和生活热水系统两个独立的液体工质换热管路，设有与采暖系统的液体工质换热管路相接的采暖出水管9和回水管10，设有与生活热水系统的液体工质换热管路相接的热水出管7和冷水进管8。采暖系统和生活热水系统不同时工作，且采暖和制冷时，优先保证生活热水系统的温度供应。The heating system includes a tank shell with dual outputs connected to the heat pump cycle unit. The tank shell is provided with a refrigerant inlet and a refrigerant outlet. An independent liquid working medium heat exchange pipeline is provided with a
在冷水进管和回水管上均装有水泵。Water pumps are installed on the cold water inlet and return pipes.
其采暖系统和生活热水系统不同时工作，Its heating system and domestic hot water system do not work at the same time,
采暖系统工作时，对应的回水管上的水泵工作，通过回路中的液体工质带走能量；生活热水系统工作时，对应的冷水进管上的水泵工作，通过回路中的液体工质带走能量。When the heating system is working, the water pump on the corresponding return pipe works, and the energy is taken away by the liquid working medium in the circuit; when the domestic hot water system is working, the water pump on the corresponding cold water inlet pipe works, and the liquid working medium in the circuit brings energy take energy.
两个独立的液体工质换热管路为两根独立的金属管或是由一根金属管分隔为两段管路构成。冷媒分配均匀，且采暖和制冷时，能够优先保证生活热水系统的温度供应。The two independent liquid working fluid heat exchange pipelines are composed of two independent metal tubes or a metal tube divided into two sections of pipelines. The refrigerant is evenly distributed, and when heating and cooling, it can give priority to ensuring the temperature supply of the domestic hot water system.
在采暖季机组持续工作在制热模式，并且优先保证生活热水侧的温度供应。由于热泵机组的制热功率较高（一般为10Kw以上），生活热水缓冲水箱很快就能达到设定温度从而退出生活热水模式；只会引起采暖室内的温度小幅度变化，不影响采暖舒适度。During the heating season, the unit continues to work in the heating mode, and gives priority to ensuring the temperature supply of the domestic hot water side. Due to the high heating power of the heat pump unit (generally above 10Kw), the domestic hot water buffer tank can quickly reach the set temperature and exit the domestic hot water mode; it will only cause a small change in the temperature in the heating room and will not affect the heating comfort.
在制冷季机组会自动进行制冷制热模式转换，并且优先保证生活热水侧的温度供应。由于热泵机组的制热功率较高（一般为10Kw以上），生活热水缓冲水箱很快就能达到设定温度从而推出生活热水模式；只会引起采暖室内的温度小幅度变化，不影响制冷舒适度。During the cooling season, the unit will automatically switch between cooling and heating modes, and give priority to ensuring the temperature supply of the domestic hot water side. Due to the high heating power of the heat pump unit (generally above 10Kw), the domestic hot water buffer tank can quickly reach the set temperature to launch the domestic hot water mode; it will only cause a small change in the temperature in the heating room and will not affect the cooling comfort.
在采暖季，当空气源热泵主机需要化霜时优先启动生活热水冷凝器回路提取生活热水水箱中的热量进行化霜，将化霜对室内采暖温度的冲击降到最低。In the heating season, when the air source heat pump host needs to defrost, the domestic hot water condenser circuit is first started to extract the heat in the domestic hot water tank for defrosting, which minimizes the impact of defrosting on the indoor heating temperature.
其冷媒回路所有部件都在工厂中完成安装、调试；避免了现场安装冷媒管路可能存在的泄露问题。All components of the refrigerant circuit are installed and debugged in the factory; the leakage problem that may exist in the on-site installation of the refrigerant pipeline is avoided.
系统处于制取热水模式时，水热换热器打开状态，冷暖换热器关闭状态，空气热换热器打开状态。水热换热器的水泵打开，冷暖换热器的水泵关闭。压缩机从进口吸入低温低压的气态冷媒，经压缩后形成高温高压的气态冷媒进入到水热换热器中，冷媒和水热量交换，水温升高，冷媒变成中温高压的气态冷媒，中温高压的气态冷媒通过冷暖换热器后，通过过滤器进行过滤，通过膨胀阀进行节流变成低温低压的液态冷媒，低温低压的液态冷媒通过空气热换热器吸收空气的热量后蒸发为低温低压的气态冷媒，低温低压的气态冷媒从压缩机的进口进入压缩机中压缩，形成一个闭式循环系统。When the system is in hot water production mode, the water heat exchanger is on, the cooling and heating heat exchanger is off, and the air heat exchanger is on. The water pump of the water heat exchanger is turned on, and the water pump of the cooling and heating heat exchanger is turned off. The compressor sucks low-temperature and low-pressure gaseous refrigerant from the inlet. After compression, it forms a high-temperature and high-pressure gaseous refrigerant and enters the water-heat heat exchanger. The refrigerant and water exchange heat, and the water temperature rises. After the high-pressure gaseous refrigerant passes through the heating and cooling heat exchanger, it is filtered through a filter and throttled through an expansion valve to become a low-temperature and low-pressure liquid refrigerant. Low-pressure gaseous refrigerant, low-temperature and low-pressure gaseous refrigerant enters the compressor from the inlet of the compressor to be compressed, forming a closed cycle system.
